Ultra-thin chips combine flexibility and mechanical stability of silicon (20 μm thick) and maturity of CMOS technology. However, circuit design on bendable dies brings up new challenges that are not typically present in rigid electronics. Due to bending, variable stress emerges in silicon, changing the mobility of carriers, which may lead to inaccuracy or failure of the circuit. In order to obtain a robust, precise system, bending must be considered in the design phase prior to fabrication. This work focuses on development of a precision flexible CMOS in-plane stress sensor to measure the complex stress-displacement relationship of a Fin Ray robotic gripper without introducing nonlinearity. Within this framework, a stress-aware mixed-signal design flow is developed for the first time, demonstrating the feasibility of high performance, complex circuitry on ultra-thin chips, in turn flexible foils.Key points of this work: In-plane stress effect is maximized and irrelevant tensor components are filtered out by sensor element circuit configuration. Analysis of linearity and temperature dependence of sensor elements is performed. A stress insensitive temperature measurement method is developed. Localized temperature inquiry is enabled by a small footprint circuit, which is crucial considering the large lateral thermal resistance of ultra-thin chips. The readout circuit is desensitized to stress by using stress insensitive components in the feedback loop and additional layout considerations. The biasing circuitry is developed for minimum stress sensitivity, which enables standalone sensor operation without external components. The digital design flow is modified with minimum interference on the conventional steps avoiding extended compilation and simulation times.

The idea of writing a book on CMOS imaging has been brewing for several years. It was placed on a fast track after we agreed to organize a tutorial on CMOS sensors for the 2004 IEEE International Symposium on Circuits and Systems (ISCAS 2004). This tutorial defined the structure of the book, but as first time authors/editors, we had a lot to learn about the logistics of putting together information from multiple sources. Needless to say, it was a long road between the tutorial and the book, and it took more than a few months to complete. We hope that you will find our journey worthwhile and the collated information useful. The laboratories of the authors are located at many universities distributed around the world. Their unifying theme, however, is the advancement of knowledge for the development of systems for CMOS imaging and image processing. We hope that this book will highlight the ideas that have been pioneered by the authors, while providing a roadmap for new practitioners in this field to exploit exciting opportunities to integrate imaging and "smartness" on a single VLSI chip. The potential of these smart imaging systems is still unfulfilled. Hence, there is still plenty of research and development to be done.

CMOS Circuit Design for RF Sensors is about CMOS circuit design for sensor and actuators to be used in wireless RF systems. The main application is implantable transducers for biomedical purposes such as sensing of nerve signals and electrical stimulation of nerves. Special focus is put on the power and data link in a wireless system with transducers which are powered via the RF link. Novel principles and methods are presented for the regulation of power to the sensors and for the distribution of data and power in an implanted transducer system. One of the main problems in such systems is the transmission of power via an RF link. This problem is analyzed in detail and solutions incorporating an RF magnetic link to the transducers are identified. The theoretical results are supported by experiments from CMOS chips including a system chip for functional electrical stimulation (FES).

In light of decreasing feature size and greater sophistication of modern processing technology, CMOS has become increasingly attractive, pro- viding low-power (at moderate frequencies), good scalability, and rail-to- rail operation. For many designers, particularly those approaching VLSI from a system viewpoint, previous experience has been mainly with ratioed NMOS design, and so there is a need to buildon this experienceand make a naturaltransition into CMOS design. Indeed, there ismuch that can bebor- rowed from NMOS experience, mainly centered around the techniques for creating N channel pulldown structures. Based on these contributions, CMOS has now grown to the point where there are several circuit styles which have evolved, and these are amply described in this book. Starting at the level ofthe individual MOSFET, basic building blocks are described, as well as the variety of CMOS fabrication processes in contemporary usage. Circuit style issues are then expandedto providethe user with several useful design methodologies, andmuchcareisgiventoelectricalperformancecon- siderations, including characteristics of interconnect, gate delay, and I/O buffering. This understanding is then applied to macro-sized components, including array multipliers, where the reader acquires a unified view of ar- chitectural performance through parallelism, and circuit performance through scrupulousattentionto device sizingandcontrolofparasiticcircuit elements. In addition, layout techniques to avoid latchup, a consideration not previously encountered by NMOS designers, are given careful treatment.
